He aha ka Epoxy Conformal Coatings no ka PCB?

ʻO nā uhi kuʻuna he kiʻiʻoniʻoni polymer i hoʻohana ʻia i nā ʻili o ka papa kaapuni i paʻi ʻia e pale iā lākou mai nā mea ʻino e like me ka makū, ka wela wela, a me nā kemika. He lahilahi kēia mau kiʻiʻoniʻoni i hiki iā lākou ke kūlike me nā ʻano papa like ʻole a me kā lākou mau mea. ʻO ka papa pale a lākou e hāʻawi ai he mea koʻikoʻi ia i ka hōʻoia ʻana i ka pono o ka uila, hana a paʻa.

ʻO ka epoxy conformal coating kahi hui ʻelua ʻāpana e hāʻawi i ka ikaika a me ke kū kūʻē ʻana ke hoʻohana ʻia. Hoʻōla maʻalahi ka hui ʻelua ʻāpana a kū i ka haʻalulu, ka haʻahaʻa, ke komo ʻana i ke kemika, a me ka abrasion. Hiki ke ʻike ʻia kēia ʻano uhi ma ke ʻano he ʻāpana ʻāpana hoʻokahi akā pono e hoʻōla ʻia e ka ʻike UV a i ʻole thermally. Loaʻa i nā mea ʻelua ke kūpaʻa kemika a me ka wela a paʻa a paʻakikī.

ʻO nā pōmaikaʻi 

ʻO ka hilinaʻi kūpaʻa wela o nā uhi epoxy e kaulana ai lākou i nā noi ʻoihana, automotive, a me aerospace. Hoʻohana ʻia lākou e like me ka hoʻomaikaʻi ʻana i ka primer adhesion ma nā ʻili metala, ʻoi aku ka maikaʻi o ka poʻe i ka corrosion. ʻO kekahi mau kini metala a me nā ipu hao nō hoʻi kēia i uhi ʻia i loko o lākou ma ke ʻano he mea e pale ai i ka ʻōpala, ʻoi aku ka nui o nā mea i hoʻohana ʻia no nā meaʻai waikawa e like me nā tōmato. No laila, ma waho aʻe o ka hoʻohana pono ʻana i nā PCB, ʻoi aku ka maikaʻi o ka uhi conformal i nā wahi ʻē aʻe. He koho maikaʻi ia ma muli o kēia mau pono;

• He mea maʻalahi ka hoʻopili ʻana i ka epoxy coating
• Loaʻa iā ia ka hoʻololi aniani kiʻekiʻe me 50-90 degere C nā waiwai wela
• Loaʻa ka hoʻopili ʻana i ka dielectric constancy a me ke kūpaʻa insulation
• He ʻokoʻa kona ʻano hoʻoheheʻe ʻana a me ka mālama ʻana
• Hāʻawi ia i ka pale pōkole pōkole a hoʻohana mau ʻia ma ka 150 degere C
• He haʻahaʻa ke kumu kūʻai o ka uhi ʻana i ka urethane a me ka silicone
• Hiki iā ia ke hoʻomaʻemaʻe me ka ʻole o nā mea hoʻoheheʻe e hoʻomaikaʻi i kāna hoʻoheheʻe wai emulsion

ʻO nā meaʻino 

ʻAʻole kānalua ka paʻakikī a me ka lōʻihi o nā uhi epoxy a hāʻawi i ka pale hydrophilic polar. Eia naʻe, loaʻa i ka coating kekahi mau hemahema e pono ai ʻoe e ʻike e pili ana i ke kūʻai ʻana a noi. ʻO nā hemahema o kēia hoʻopili conformal e hoʻokomo i nā hiki ke neʻe i ka wai ma lalo o nā uhi. Hoʻonui ka neʻe ʻana i ka permeation, a hiki i kēia ke alakaʻi i nā pilikia e like me:

• Wehe i ka uhi pale ma ka hui
• ʻO ka pealing o ke kiʻi conformal pale
• Hoʻokomo ʻia e nā mea ʻino o waho
• ʻO ka hana a me ka hoʻohaʻahaʻa ʻana i ka corrosion

ʻO ka hopena, ʻaʻole pono e koho i ka uhi epoxy no nā mea hana a me nā ʻāpana e hana ana i nā kūlana pili wai. Hoʻopili pū ia i nā kūlana noe a me nā kūlana paʻakai. ʻO nā hemahema ʻē aʻe:

• He paʻakikī ke hoʻoponopono a hana hou ʻana i ka uhi Epoxy ma muli o kona paʻakikī a me ka paʻa o ka ʻili
• Hiki ke emi i nā kaʻina hana polymerization
• ʻO nā mahana wela e hōʻemi i nā pae kūʻē koʻikoʻi
• ʻO ka loaʻa ʻole o ka ʻike UV i kekahi mau epoxies e hōʻino i nā uhi inā e ʻike nui ʻia lākou i ke kukui UV.
• ʻAʻole hilinaʻi ʻia i ka pale ʻana i ka ulu ʻana o ka whisker tin a me nā hopena

hōʻuluʻulu manaʻo 

He lōʻihi loa ka pale ʻana o ER a kūʻē i ka kemika, ka haʻahaʻa, ka haʻalulu, a me ka pōʻino abrasion. Akā ʻaʻole hiki ke nānā ʻole ʻia hiki ke hoʻemi ʻia ko lākou kūʻē ʻana ma luna o nā wela kiʻekiʻe loa. ʻO ke ʻano kiʻiʻoniʻoni lōʻihi e hana kūʻē iā ia, e hana paʻakikī i ka hoʻoponopono ʻana. I ka hana ʻana me kēia ʻano uhi conformal, pono ʻoe e mālama pono i nā kaʻina hana a pau i koe ʻole nā ​​hemahema, a ʻaʻohe pono no ka hoʻoponopono a me ka hana hou. ʻO kahi uhi hiki iā ʻoe ke hilinaʻi me ka noi kūpono a hoʻohana i nā kūlana kūpono.
